if you use a postprocessor which was created in an earlier NX version it's needed to update the postprocessor to latest library version. So normally when you installed NX12.0.2 the libraries are updated in the mach/resource/post_configurator folder. That means if you create a new postprocessor this one should have version 4.4.4. Also we updated most of the OOTB sample machines to latest version.

Can you please check the version of the lib_sourcing.tcl?

If this is the case you can update your existing postprocessor with newest version. For this i've attached a small guide how to do.

Hope that will helps.

Edit: I recommend to do a backup of the existing postprocessor before executing the update.

Thanks a lot for the video. However, it is unfortunate that my CAMExpress Advanced license does not allow me to see the debugging area. SiemensPLM's policy to not allow debugging for such a fundamentally important tool for developing your own post is questionable.

I've got back to work yesterday and have got the post working but without machine code. Am still working on it.

thanks for this honestly feedback about the licensing of features in Post Configurator. I don't want to start a discussion here about the license model and i will forward your feedback.

Not sure about the exact costs of the Full license but i think for the invest you get functionality which will help you. Maybe you can ask your local contact for a Testlicense and then decide it later how to go on there.
